Crystal structure identification using x-ray diffraction technique is known to be hard work if multicomponent specimens should to be analyzed. We must use a lot of fitting parameters, resulting in long analyses time and ambiguity in the component identification. In this work, we propose a high-speed and objective analysis of XRD pattern using a spectrum database.
